I haven't looked into Wiseco recommendations for years and can't remember if they even recommended different ring gaps than stock years ago? 

Off the top of my head, Yamaha recommended gaps for the 175 are in the 0.008" to 0.016" min/max range?  I remember getting Wiseco rings decades ago that had a gap closer to 0.002" out of the box, they needed fitting.
